Arum concinnatum is a robust-growing Arum from the Aegean with large lightly-speckled foliage and an inflorescence with a greenish-yellow spathe and yellow spadix. The spathe can be variable in colouration and sometimes has a purplish tinge. It usually has a purple margin similar to Arum hygrophilum. Like most Arums it is dormant during the summer and the foliage appears in autumn. It is perfectly hardy in the UK and maintains its foliage throughout frost and snow, forming a large clump. The inflorescence appears in mid-Spring.

A very easy and rewarding Arum.
